Application filed January 10, 1923.

T 0 aZZ 107mm 711- may concern:

Be it known that I, CHARLus A. MEISEL, a citizen of the United States,and a resident of Boston, county of Suffolk, and State of Massachusetts,have invented an Improvement in Apparatus for Printing NumberedImpressions, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to printing devices and more particularly todevices which are adapted to print a series of numbers on successiveimpressions and the object more particularly is to provide anarrangement of this character which will provide for one or moresupernumerary impressions between successive series of numbers withoutdanger of confusion.

My invention will best be understood by reference to the followingdescription of an illustrative embodiment thereof taken in connectionwith the accompai'iying drawings, wherein:

Fig. 1 is a diagrammatic side elevation of portions of a printing presspartly broken away to show the portion at the upper left hand part ofthe figure substantially on the line 1-1 of Fig. 2;

Fig. 2 is a longitudinal section through the numbering head shaft Fig. 2is a detail;

Fig. 3 is a section on the line 33 of Fig. 2;

Fig. 4: is aside elevation of a cam;

Figs. 5 and 6 are sections on the lines 55 and 6-6 of Fig. 2respectively; and

Fig. 7 is a section on the line 7-7 of Fig. 3.

Printing mechanisms for printing a series of consecutive numbers, as,for example, on a series of tickets or coupons, are well known as arealso means for causing an intermission of the numbering operationbetween the printing of successive series. By way of example I willrefer to the patent to Charles A. and Francis Meisel, 1,186,020,

June 16, 1916, and the patent to Francis Meisel, 1,03%,637, August 6,1912. In view of the art as disclosed particularly by these patents, theillustration and description of certain mechanisms herein will beconsider- Serial No. 611,901.

ably abbreviated. By way of example we may consider the printing on acontinuous web of sets of coupons, the elements of each set oi which areto be consecutively numberethsay from 1 to 100. That is, the first onehundred coupons will be numbered serially and then thcnumberingmechanism will be manipulated to cause the series to repeat. Tofacilitate the separation of the coupons belonging to individual seriesfor collection and assembly it is desirable to have a certain spacebetween successive series and this may be efiected, as in the patentsreferred to. by stopping the operation of the numbering mechanisms sothat the last number of the series will be repeated a certain number oftimes. As a result of this operation there are a number of waste orextra coupons in the series and to avoid confusion and also because whathave herein been referred to as coupons may be certificates of value, Iprovide in accordance with my present invention means for printing onthese duplicate elements with an auxiliary printing device which mayindicate that they are not true and valid elements of the series butmerely waste. In the example of my invention here chosen for purposes ofillustration the word Void is printed on the coupons of duplicatenumber.

Referring particularly to Figs. 1 and 2, I herein show certain elementsof a numbering printing attachment bearing considerable resemblance tothat shown in the patent to Francis Meisel 1,034,637 above referred to.Opposing a suitable impression cylinder 9 there may be arranged a shaft11 carrying a suitable number of numbering heads 13 of well known type.To cause the operation of these numbering heads so that they will printsuccessive numbers each head or set of heads may be controlled by a camarrangement embodying the relatively stationary member 14 and theslidable member 15 which are provided with the grooves 17 and19 in theform of circular arcs. When the elements are spaced from each other asin Fig. 1 the grooves 17 and 19 form an eccentric track adapted toactuate the pawl lever of the numbering head as described in the patentsabove referred to but if the member 15 is caused to approach the memberlet the two grooves will form a circular track which will be withouteffect on the numbering head. The member 15 may be provided with a rack21 which meshes with a toothed shaft extending across the press from oneframe to another, the rack herein engaging with the underside of thisshaft. If the shaft 23 is given a partial rotation clockwise from Fig. lthe 'am section 15 will be moved to the left and the operation of thenumbering head will be stopped and until the reverse action takes placethe same number will be printed repeatedl Herein theshaft 28proj acts atthe side of the machineand provides at the outer end a pinion with whichmeshes a sector gear lever which may be rocked by the lever arm 2?having a nose or follower 29 cooperating with a cam 31 toward which thelever is pressed by a spring The cam 81 is pr.- vided with a depression35 into which the nose 29 may drop and when this occurs the arm 2T willswing counterclockwise as will the sector 25 and the pinion shaft 23will be rotated. The cam 31 is rotated by a ratchet wheel 'l'operated bya pawl 39 on the pawl-carrying lever ll which isintermittentlyoscillated by connecting rod from a crank on theimpression cylinder 9. On each rotation of the impression cylinder 9 andin definite relation to the number of impressions the ratchet wheel andconsequently the can'i 31 is incrementally advanced and thus after acertain number of impressions has been made and the desired numericalseries is completed the notch in the-cam will come opposite the followeror nose 29 and the mechanism will be operated'to shift the cam part 15and stop the operation of the'nnmbering head which will thenprint thesame number repeatedly for a certain number of impressions until thefollower or nose29 rides out of the recess 1 35 after which the serieswill be repeated.

Inthe drawing I have also illustrated a manual adjusting meanssubstantially as shown in the patent to Francis Meisel, No. 1,034..637,above'referred to.

in accordance with my invention I pro vide a suitable printing mechanismgoverned. in opposite phase to the numbering head or heads to 'printsuitably on the work when the i'unnbering head is no longer operatingand is printing duplicate numbers. .e'terring particularly to Figs. 2and 6 in the present embodimentof my invention I have shown a cylinderor wheel mounted on the numbering head shaft 11 and opposing theimpression cylinder 9 and mounted radially in this wheel 45 are providedtype-carrying plungers 47 which may carry suitable printing types 49 ontheir-faces and herein I have shownsuch a type bearing the legend Voidas shown in Fig; 2. In the embodiment of the invention shown fourimpressions are made or four coupons or the like printed on eachrevolution of the printing couple and l tl'lGl'QfOlG show here fourtype-carrying plnngers. These plungers 47 are provided with stems 5ihaving heads on which act helical sprin s normally tending to draw theplunger-s radially inwardly to a position in which they will not printas they pass the impression cylinder and means are provided whereby theplungers may be forced radially outwardly at proper times to permit themto art. in the present in stance this ma y be effected by means of camsacting on the heads 55 of the plungers and which may take the form ofrods or shafts housed in suitable grooves in the numbering head shaft 11and having flattened sides 9 as best shown in Fig. 6. It will. beunderstood from that figure that if the flattened s s of these rods arepresented to the heads the springs will draw the plungers inwardly andthe types will be in inoperative position but if the rods are turned asshown at the left of Fig. tithe plungers will be forced. outwardly andthe types will be in operative position.

This operation of the plungers is effected in opposite phase with thecontrol of the numbering head through the cam grooves 17 and 19 andconveniently through the same pinion shaft 23 and for this purpose theends of the rods 57 may be formed as piniens (it (see Figs. 2 and 7) andmay be rocked by segments 6 pivoted on a collar or flange 63 carried bythe shaft 11. and adapted to be operated by the levers 67 carryii camrolls 69 and suitable cam means su' h as i will hereinafter describe mayact on the can rolls 69 at proper times governed by the turning of thepinion shaft 23. Referring now more particularly to Figs. 2 3 and 7, Imay mount a holder 71 on a sleeve or bushing 72 surrounding the end ofthe shaft it which may he provided with a dove tailed groove '73 (seeFig. 3) adapted to receive a corresponding rib on a slidable cam holder7 conveniently of crescent or partly annular form to adapt it partly toembrace the shaft it as shown in Fig. The cam holder has an arm carryinga rack 77 meshing with the pinion shaft 23 preferably at the upper sidethereof so as to be operated in opposite phase to the rack 23controlling the numbering head.

Carried by the cam holder ronveniently at. the inner side thereof is acam 79 shown by itself in Fig. l and which may embody a plate ofpartially annular shape conveniently provided on its inner circumferencewith a flange 31 (see Fig. 7) facilitating its support on the cam holderThe inner face of the plate 79 carries two eamming elements disposedgenerally on opposite sides of the path of the cam roll69, an innerelement 83, conveniently braced by-the rib 85. and an outer element 87.In the inner position of the cam holder the cam rolls or followers (55miss the inner cam 83 but are forced inwardly by the cam 87 and the rods57 are rocked to the position shown at the right and top of Fig. 6wherein the types l9 are drawn inwardly to an inoperative position andwill not cooperate with the impression cylinder 9. This is the normalposition of the parts while the numbering ope-ration proceeds. hen,however, the pinion shaft 23 is rotated to shift the cam controlling thenumbering heads so that a number isrepeated, the clockwise revolution ofthe shaft 23 viewing Fig. 3 will draw the cam holder 7 and its camtoward the right and the cam rolls 69 will then miss the cam 87 but willcome in contact with the cam 83 which will cause the rods 57 to berocked to the position shown at the bottom and left of Fig. 6 projectingthe printing types 49 out to a printing position. When the serialprinting of numbers is resumed, the cam holder is shifted back to theleft and the cam element 87 acts to retract the printing types l9 again.In Figs. 3 and 6 we may imagine that this operation has just taken placeand that the printing of a series of numbers is to re ommence after ahalf revolution of the printing couple. Before the cam was shifted allthe printing types were at their outward position but the plungers shownat the top and left after having printed have now been acted. upon bythe cam element 8? and are retracted. The type carried by the plungershown at the bottom of Fig. 6 is about to print and after it has done soit also will be retracted; as will the plunger shown at the left Afterthe series of numbers have been printed and the cam element 83 isbrought into operative position to act on the cam roll 69, each plungeris moved to outward position substantially as it passes the three oclockposition in Fig. 6 and prints as it reaches the six oclock position. i

I have described in detail the particular mechanical elements which areutilized in the embodiment of my invention here shown.
